PAPER-FEED DEVICE FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 452,470, dated May 19,1891.

Application filed May 5, 1890. Serial No. 350,553. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES I1. W INTON,

a citizen of the United States, and JOHN S. LUOOGK, a subject of theQueen of Great Britain, both residing at Allegheny, in the county ofAllegheny, State of Pennsylvania, have jointly invented a new and usefulPaper- Feeding Device for Type-WVriting Machines, of which the followingis a specification.

Our invention consists in an automatic paper-feed for type -writingmachines, which moves with the paper-carrying device of said machines,and which is operated simultaneously with and by the same power andmeans which actuate the paper-feeding roll of said type-writing machinesin Suchmanner as to co-operate with the paper-feedingdeviccs of saidtype-writing machines in brlng ng the paper used thereon into properposition to take the impression of the writing types thereof.

The object of our invention is to provide the means to automaticallyfeed and adjust paper to the paper-feeding devices of typewritingmachines, so that the present invention co-operating therewith Wlll adust and feed the paper continuously to the proper position to receivethe impression from the machine.

In the accompanying drawings, Figure 1 shows a side elevation of ourinvention attached to the paper-carriage of a ty'pe-writin g machine.Fig. 2 is a central section of the same. Fig. 3 is a plan view ofFig. 1. Fig. 4 is a section of Fig. 3 on line 11 II. Fig. 5 is an endview of the feed-roll of the automatic paper-feed. Fig. 6 isa section ofFig. 5.

In Fig. 1, 1 is the frame of the carriage of a type-writing machine, inwhich are sockets 1, and which carries the paper-feedin g rolls 2 and 3.

at is the lever which operates the paperfeeding roll 2, which in thewell-known manner causes roll 3 to revolve, and these rolls guide thepaper into proper position to receive impressions from the machine.

Our automatic paper-feed is constructed as follows: -A rectangular frame5, Fig. 3, is made of metal or other convenient material and is providedwith two or more curved braces 6 6, situate a short distance from theends thereof. (See dotted lines, Fig. 3.) Each of these braces has lugs7, which have a shoulder at 7, and are made to fit snugly into sockets 1of frame of the carriage 1. The frame 5 is also extended opposite thebraces 7 and provided with sockets 8, Whose use will be hereinafterexplained. The ends of the frame 5 are provided with holes 9 for thereception of shaft 10, carrying roll 11. Plate 12, forming a table, overwhich the paper is pushed, is fastened to the front side of frame 5 ofthe feed and extends the full width of the same Within. a short distanceof roll 11 on one side and such a distance in front of frame 5 as toproperly support the paper fed to the feedingrolls2 and 3 of thetype-writing machine.

To each end of frame 5 is attached a plate 13, having slotted lugs 13',and on the inside slots 13 Fig. 2, the slots in 13 each having a slightoffset. A ribbed plate 14 is made of a length to easily fit in betweenthe end plates 13, and at each end is provided with lugs 14., which areof such size as to be insertible into the slots in 13' and be secured inthe offsets thereof. Plate 14 is also provided with a thumb-screw 15, towhich is fastened a curved spring 16, and also two holes 14 throughwhich guides 17 pass. The ends of spring 16 are .slotted to provide forthe movement of the same when different degrees of pressure are appliedto the spring by means of screw 15. fixed in plate 18, and may be astrip of any convenient material.

To the end of shaft 10, Fig. 5, is fixed a disk 19, to which is fasteneda ratchet-wheel 20 and a pawl 21, having a retracting-spring 22. To disk19 is also connected a movable link 23, having at its free end coupling24, Fig. 1, which is fixed to the line-space lever 4: of thetype-writing machine and fixed in position by set-screw 25. The size ofratchet 20 and the number and size of its teeth, the length of link 23and the point of its connection with lever A must be so proportionedthat the paper will be fed from the automatic feed at the same rate thatthe feed-rolls of the typewriting machine feed it into said machine.Plate 26 is made of any material, preferably light metal, having a brace26' on its under side whose ends are formed into lugs to fit sockets 8of frame 5. It is provided with slots 26 Guides 17 are put through holes14 and 27 is a strip of metal to which are fixed two upright pins 28 andon the other side two screws 29, on which thumb-screws 30 are placed tohold and adjust strip 27in any desired position in slots 26 The lengthof plate 26 may vary to accommodate different sizes of paper.

To use our invention the paper to be used on the type-writing machine ispunched with two holes, which are to be the same distance from eachother as the pins 28. The paper is then placed on pins 28 and the plate26 placed on the frame of the carriage by placing lugs 26' in sockets 8thereof, plates H and 18 having been previously removed, and so that thepaper shall rest on roll 11 and extend to plate 12. Plate 18 is thenplaced between end pieces 13 and on top of the paper and plate 14slipped into the slots of said end pieces, when the pressure between thebottom sheet of paper and roll 11 can be regulated by spring 16. Theconnection between lever 4 and ratchet 20 having been made in the mannerhereinbefore described the paper will by reason of the friction betweenthe bottom sheet and the roll 11, caused by the pressure of spring 16,be drawn off of pins 28, they cutting through the same, and be fed sheetby sheet and adjusted automatically for the type-writing machine tocarry it into proper position to take the impressions from the type ofthe machine.

The advantages claimed for our invention are the saving of time andsecuring a proper adjustment of each sheet of paper fed into thetype-writing machine. These advantages are peculiarly serviceable in thetelegraphic business, where itis now impossible to receive commercialmessages using the type-writer because of the delay occasioned bymanually feeding and adjusting each sheet of paper used. This delay isobviated by the use of our present invention.

lVe have here shown ourinvention applied to a well-known class oftype-Writing machines, but do not wish to be confined strictly to thedevices here shown and described to show the principle of our invention,the invention being as hereinbefore described and applicable to manyother classes of type-writing machines by the devices here shown ortheir equivalents.

\Vhat we claim as our invention, and desire to secure by Letters Patent,is-

1. The combination of a type-writing-machine carriage with a paper-feedhaving a paper feed roll mounted thereon, and the means whereby the rollof said feed is operated by and simultaneously with the paper roll ofsaid type-writing machine, substantially as and for the purposesdescribed.

4. A paper-feeding device for type-writing machines,having aframeadaptedto be mounted on the carriage of said machine, a paperfeed roll mountedon said frame, the shiftinglever of said carriage of the type-writingmachine, and the connect-ions between said roll and said lever,substantially as described.
